4 Executive summary We ran a behavioural insights trial with KiwiSaver provider Kiwi Wealth. The trial ran for seven months, from August 2016 to February The aim of the trial was to see if behavioural prompts increased the number of active fund choices members made. To test this, prompts were included in the first communication KiwiSaver default members received from Kiwi Wealth. There were 3,427 participants. Half of the default KiwiSaver members received the original communication (the control); the other half received the revised communication (the treatment). Members received either an or a letter. People who received the revised treatment communication were 47% more likely to make an active fund choice than those who received the control one. The result was statistically significant for those who received an or a letter but overall those who received an were more likely to make a change than those who received a letter. As part of the research, we also looked to see if results varied across the months of the year and whether people who received the treatment communication were more likely to log in to their Kiwi Wealth account. We also looked at whether people were more likely to stay with Kiwi Wealth. Our analysis shows the number of fund changes reduced towards the end of the trial possibly due to inactivity around Christmas and New Year. There was no statistically significant difference overall between the control and treatment group for the number of people logging in to their Kiwi Wealth online account. However, there was a statistically significant difference in account closures, with those receiving the treatment communication more likely to stay with Kiwi Wealth. This report provides a summary of the results of this trial. Due to its success, the Kiwi Wealth team has decided to continue using the treatment communication for all new default members. We would like other KiwiSaver providers to make similar changes to their communications. The approach can be adopted across any member communications and the changes are quick and low cost. We are also keen to continue to learn from what works, by running further trials with financial service providers. By sharing the results, we want to encourage providers to improve their communications with their KiwiSaver members. Encouraging fund choice in KiwiSaver Page 4

5 About the trial Why the trial was necessary There are currently around 2.6 million members in KiwiSaver New Zealand s work-based retirement savings initiative. Approximately 450,000 of them are in a default fund. The default fund was designed as a temporary holding fund for new members who hadn t yet made an investment fund decision. It is conservatively invested and does not suit everyone. Often members in conservative funds will find their savings have not grown enough for them to enjoy a comfortable retirement. Our Strategic Risk Outlook, published in February, highlighted that New Zealand is experiencing a significant change in its population demographics. More than 25% of our population will be aged 65 or over by From 2040, under current proposals, NZ Super will rise to 67 years of age, making it even more important for New Zealanders to be adequately prepared financially for their retirement. Default members typically have lower levels of knowledge and interest about KiwiSaver. This increases the risk they will not have adequate savings at retirement. New Zealand s nine default KiwiSaver providers each have an obligation to help their members make an active choice about the best type of fund to suit their savings goals. Our KiwiSaver report 2016, reported on the success of these efforts. It shows most default KiwiSaver members are not choosing their own fund. While one provider achieved 22% of members making a fund choice, the others ranged from 1 to 8%. Most providers were clustered around 3 to 4%. We want this number to increase and believe providers can do more to encourage their members. We decided to run a formal trial to test whether making changes to new member provider communications could improve these results. The trial was run after the release of our April 2016 white paper which explained how behavioural biases can impact investment decisions. What we wanted to find out The main aim of the trial was to see if using behavioural prompts in the welcome communication to default KiwiSaver members would encourage them to choose their own fund. We also wanted to know: Does the format of the communication affect the result for example, does receiving an rather than a letter make any difference? Does the timing of the communication affect its result? Are people more likely to visit Kiwi Wealth s website if they receive the treatment communication? Are people more likely to stay with their default provider if they receive the treatment communication? Encouraging fund choice in KiwiSaver Page 5

6 Our approach Dr. Marcos Pelenur, a behavioural insights specialist employed by the Ministry of Business, Innovation and Employment helped us oversee the trial. Kiwi Wealth also agreed to participate in the trial. We identified Kiwi Wealth s first welcome communication for new default members as the best opportunity to encourage members to choose their own fund. and letter versions of the welcome communication were amended using the EAST framework. These are principles international studies have shown to have effective and measurable behavioural change outcomes: Make it easy We turned the long narrative form into three easy steps to follow We added links in the version so people could easily go online to complete their actions Make it attractive We framed the actions required as to finish setting up your KiwiSaver account We used a visually engaging layout Make it social We let readers know they were doing what most other New Zealanders had done in joining KiwiSaver and making a fund choice Make it timely The communication is issued when default members first join Kiwi Wealth, making it a relevant time to consider their fund choice We had a clear call to action in the subject line (in the letter we used a visual sticky note ) The next page has an example of the amended . The trial began in August 2016 and ran through until February In total, 3,427 new default KiwiSaver members received the welcome communication. Members were randomly assigned so that half received the original communication (the control) and half the revised communication (the treatment). Members who had an address received the communication by . The others received it by letter. Encouraging fund choice in KiwiSaver Page 6

8 The results - what we found Impact on member fund choice People were more likely to choose their own fund if they received a treatment communication Table 1 shows the total number of members in the control and treatment groups who made their own fund choice. Only one person from the control group chose not to change their investments. Table 1: Number of members who made a fund choice Letter Total Control Treatment Statistical results We used two statistical models to analyse the data. Simple model This model looked at whether people who received the treatment communication, across both and letters, were more likely to choose their own fund. Full model This model analysed whether the type of communication ( or letter) made it more likely a member would choose their own fund and whether the results changed across certain months. Find out more about the two different models in Appendix 1. Analysis from the simple model showed there was a statistically significant difference (p < 0.025). As shown in figure 1, people who received the treatment communication were more likely to choose their own fund. Encouraging fund choice in KiwiSaver Page 8

9 Figure 1: Probability of members in the control or treatment group choosing their own fund On average, the probability of the treatment group changing their fund choice was 47% higher than for those who received the control communication. Results from the full model analysis show people who received the treatment communication were more likely to choose their own fund than those in the control group regardless of whether an or letter was issued. Overall, however, people who received a treatment were more likely to choose their own fund than the treatment group who received letters, as shown in Figures 2 and 3.

10 When the results were examined across the months of the year, the full model shows people are less likely to choose their own fund towards the end of the trial. This may be due to inactivity around Christmas and New Year. Impact on first logins to Kiwi Wealth s website People who received letters were statistically more likely to log in than those who received s Table 2: number of first logins Letter Total Control Treatment Statistical analysis A simple model was used to determine whether receiving the treatment significantly affected the probability that a person would log in to their Kiwi Wealth online account. The model found no statistical difference overall. A person that received the treatment communication was not more likely to log into their Kiwi Wealth account. However, the results did show if the person received a letter they were more likely to log in than those who received an .

11 Impact on account closures The treatment communication encouraged loyalty to Kiwi Wealth Table 3: Number of people who closed their accounts with Kiwi Wealth Letter Total Control Treatment Statistical analysis We analysed whether receiving the treatment communication made it more or less likely for a member to close their Kiwi Wealth account. We found a statistically significant difference in account closures between the treatment and control group (p < 0.05), as shown in figure 6. Figure 6: Probability of members closing their Kiwi Wealth account On average, the probability of the treatment group closing their account with Kiwi Wealth was 20% less than those who received the control communication.

12 Conclusion and next steps Due to its success, the Kiwi Wealth team has decided to continue using the treatment communication for all new default members. They are now reviewing all of their existing communications to identify opportunities where using this approach could add value. We would like other KiwiSaver providers to make similar changes to their communications. The approach can be adopted across any member communications and the changes are quick and low cost. We would also be interested in seeing whether further interventions, like follow-up phone calls, could improve results. Direct engagement by phone Providers who currently call members tell us that up to half of the people they reach end up choosing their own fund. However, many providers are not resourced to do this and often they do not have up-to-date contact details. We are keen to explore other more cost-effective ways of following up with members. This trial shows that simple changes can increase the number of KiwiSaver members who decide to choose their own fund. We are keen to see what else providers can do to further improve these results. We welcome the opportunity to work with other providers on similar trials that help members make the very important decision to choose their own fund. Encouraging fund choice in KiwiSaver Page 12

14 Appendix 1: Analysis models The statistical analysis was conducted using a binomial logit regression model. Model fit was tested against a null model to ensure the predictors fit significantly better than a model with just an intercept. The null hypothesis (H 0 ) is that there is no difference between the probabilities of switching in the control or treatment group (ie they are the same). Results show a statistically significant difference, therefore the null hypothesis is rejected. About the models used Analysis of fund choices The simple model looked at whether receiving treatment significantly affected making an active choice. Model specification: ActiveChoice (yes/no) ~ group (control/treatment) The full model controlled for the type of communications version sent ( or letter). It also controlled for month and communications version. Model specification: ActiveChoice (yes/no) ~ group (control/treatment) + commsversion ( /letter) Model specification: ActiveChoice (yes/no) ~ group (control/treatment) + commsversion ( /letter) + month An interaction term was tested between group assignment and communications version and no statistically significant result was found. This indicates the treatment is just as likely to work across both and letter groups. Analysis of first logins to Kiwi Wealth This model controlled for group assignment (control/treatment) and communication version ( or letter). Model specification: ActiveChoice (yes/no) ~ group (control/treatment) + commsversion ( or letter) Analysis of number of accounts closed This model controlled for group assignment, as there was no statistically significant (p < 0.05) relationship found for communication version. Model specification: activechoice (yes/no) ~ group (control/treatment) + commsversion ( or letter) + month Encouraging fund choice in KiwiSaver Page 14
